Guida Definitiva alle Estensioni di Dominio (TLD)

Le estensioni di dominio, o domini di primo livello (TLD per Top‑Level Domains), costituiscono l'ultima parte di un nome di dominio (ad esempio .fr o .com). Dalla creazione di Internet, il loro numero è esploso: accanto alle estensioni storiche come .com, .net o .org, oggi troviamo centinaia di nuove estensioni tematiche (.dev, .shop, .paris, ecc.) oltre a estensioni internazionali in caratteri non latini.

Questo articolo raccoglie la totalità delle estensioni attive catalogate dall'IANA alla data del 20 maggio 2025 , ovvero 48 h prima della pubblicazione di questo articolo. Per ogni estensione, troverai un semplice inventario alfabetico; per approfondire (politiche, registro, disponibilità), consulta le schede ufficiali dell'IANA.

Come vengono classificate le estensioni?

• gTLD (generic TLD): estensioni non legate a un paese (.com, .info, ma anche .app o .tech).
• sTLD (sponsored TLD): gestite da un'entità specifica (.edu, .gov, .museum, ecc.).
• ccTLD (country‑code TLD): due lettere corrispondenti a un paese o territorio (.fr, .ca, .uk…).
• IDN TLD: estensioni in scrittura non latina, tecnicamente codificate in punycode (es. xn--80asehdb per « .москва »).

Alcune cifre rapide (IANA, 20 maggio 2025)

• Numero totale di estensioni: 1440
• gTLD (senza IDN): 1041
• ccTLD: 248
• IDN TLD: 151
